I added the information for the activemq to jndi.properties file. Also I
changed the script file accordingly and the thrift xml.

Subject: Re: How to use the Load Balancer with openstack
Hi Athanasios,
It's nice to hear that you are using the latest codebase, it has three load
balancing options:
1. Stratos Load Balancer
2. Nginx (via extension)
3. HAproxy (via extension)
First you could try to run either of these against your Stratos deployment and
see whether they are working as expected (before trying the puppet module).
Load balancer only requires ActiveMQ and CEP information (IP, port) to run.
Do a complete build and find 1 in the following folder:
https://github.com/apache/stratos/tree/master/products/load-balancer/modules/distribution
Update loadbalancer.conf and thrift-client-config.xml with the above values and
start the product.
Thanks

Hi there,
We are trying to install Stratos 4.1.0 and ok we got over some bugs in the
files. More or less we can create many cartridges and use them with
applications. But we need a load balancer now connected with a ghost
application integrated with nodejs. What is the lb module in the puppet master
modules and what is the haproxy. How we will subscribe the application we need
to the load balancer and access the load balancer and redirect us to the
multiple instances of the application above. Is there any guide we can use?
Many thanks in advance
Athanasios Tsitsipas
